PURPOSE
To evaluate the influence of group and individual education on shade matching quality using a visual color competency test to match shade tab pairs from two Vita classical A1-D4 shade guides.
METHODS
60 dental students, 21-25 years old (39 females, 21 males) participated in the study. All participants passed a color deficiency test before the experiment. The examination was voluntary and approved by the corresponding Ethics Committee. Students were randomly divided into three groups (n=20): one control group, NE (no education) and two experimental groups - GE (group education) and IE (individual education). The study was performed in three phases. In the "before" (B - Phase 1) and "after" (A - Phase 3) phase, all groups had to match 16 pairs of tabs from two Vita classical A1-D4 shade guides, with the shade designations hidden by custom letter markings. All tabs were mixed on a gray surface illuminated by color-correcting light. In Phase 2 (between B and A), GE had only group education, while IE received additional individual education and training. The control group did not participate in Phase 2. Means and standard deviations were calculated, and differences were compared using the one-way ANOVA, ANCOVA test, and Student t-test for dependent samples (α= 0.05).
RESULTS
The NE group matched 10.3 (3.2) and 10.4 (2.9) tab pairs in the before and after phases, respectively. Corresponding results for GE were 11.1 (2.2) and 14.4 (1.9) and 9.5 (3.6) and 15.0 (1.5) for IE, respectively. In Phase 1 (B), no statistically significant difference was recorded among the groups (P= 0.260). The experimental groups achieved a statistically significant improvement compared with the control group in Phase 3 (A) (P< 0.001). Both experimental groups achieved statistically significant improvement within the group after education, GE (P< 0.001) and IE (P< 0.001). Within the limitations of this study, it was concluded that both experimental groups had statistically significant progress in shade matching. The group that received individual education (IE) made statistically significant progress compared with the group that received group education (GE). No statistically significant difference was found in the results of the control group between Phase 1 and Phase 3 of the study.
CLINICAL SIGNIFICANCE
Improving the shade matching ability facilitates the work of dentists and dental technicians and enhances the esthetics of dental restorations.
目的
使用视觉色彩能力测试来评估小组和个人教育对比色质量的影响，以匹配来自两个 Vita 经典 A1-D4 比色指南的比色片对。
方法
60 名年龄在 21-25 岁（39 名女性，21 名男性）的牙科学生参与了这项研究。所有参与者在实验前都通过了颜色缺陷测试。该检查是自愿进行的，并获得了相应伦理委员会的批准。学生被随机分为三组（n=20）：一组对照组（NE）、两组实验组 - 小组教育（GE）和个人教育（IE）。研究分为三个阶段。在“前”（B-第 1 阶段）和“后”（A-第 3 阶段）阶段，所有组都必须匹配来自两个 Vita 经典 A1-D4 比色指南的 16 对比色片，比色片的名称通过自定义字母标记隐藏。所有的比色片都在由色光矫正照明的灰色表面上混合。在第 2 阶段（B 和 A 之间），GE 仅接受小组教育，而 IE 则接受额外的个人教育和培训。对照组不参加第 2 阶段。计算平均值和标准差，并使用单向方差分析、协方差分析检验和学生 t 检验（α=0.05）比较差异。
结果
NE 组在前后阶段分别匹配了 10.3（3.2）和 10.4（2.9）对比色片。GE 的相应结果分别为 11.1（2.2）和 14.4（1.9），IE 分别为 9.5（3.6）和 15.0（1.5）。在第 1 阶段（B），组间无统计学差异（P=0.260）。与对照组相比，实验组在第 3 阶段（A）中取得了统计学上的显著改善（P<0.001）。教育后，两组在组内均取得了统计学上的显著改善，GE（P<0.001）和 IE（P<0.001）。在本研究的限制范围内，可以得出结论，两组在比色匹配方面都取得了统计学上的显著进展。接受个人教育（IE）的组与接受小组教育（GE）的组相比，在统计学上取得了显著进步。对照组在研究的第 1 阶段和第 3 阶段之间，其结果无统计学差异。
临床意义
提高比色能力有助于牙医和牙科技师的工作，并增强牙科修复体的美观度。
